  • Patent number: 6419777
    Abstract: A method of forming a catamenial tampon is disclosed wherein the tampon is useful in preventing premature leakage of body fluid from a woman's vagina and in providing better utilization of the absorbent during use. The method includes the steps of assembling a resilient member and an absorbent to form a structure having a central longitudinal axis X—X. The resilient member can be either aligned with or offset from the central longitudinal axis X—X. The absorbent and the resilient member are rolled or folded up into an elongated softwind which has a first end and a second end. The softwind is folded upon itself such that the first and second ends are aligned adjacent to one another and the softwind contains at least two folds therebetween. The softwind is then compressed into a pledget having an insertion end and a trailing end. A withdrawal string is secured to the pledget to form a tampon. The withdrawal string facilitates removal of the tampon from the woman's vagina.

  • Patent number: 5928183
    Abstract: A tampon applicator is disclosed which includes first and second telescopically assembled members. The first member is designed to house an absorbent tampon. The first member has first and second spaced apart ends and is formed from at least two separate and distinct layers. An insertion tip is integrally formed on the first end of the first member and extends outwardly therefrom. The insertion tip is constructed from at least one of the two distinct layers and has a thickness which is less than that of the first member. The second member is telescopically mounted in the second end of the first member and is adapted to expel the tampon through the insertion tip as it is pushed into the first member.

  • Patent number: 5795346
    Abstract: A tampon is disclosed which is useful in preventing premature leakage of body fluid from a woman's vagina especially during her menstrual period. The tampon includes an absorbent and a resilient member. The resilient member is positioned on or within the absorbent and both members are rolled or formed into an elongated softwind having a first end and a second end. The softwind is folded upon itself such that the first and second ends are aligned adjacent to one another and the softwind contains at least two folds therebetween. The softwind is compressed into an elongated pledget having an insertion end and a trailing end. The resilient member is capable of expanding at least a portion of the pledget so as to prevent premature leakage of body fluid when inserted into a woman's vagina. The tampon further includes a withdrawal string for removing the tampon from a woman's vagina. The withdrawal string is attached to the first and second ends of the softwind.

  • Patent number: 5738646
    Abstract: A thermoplastic applicator is disclosed which exhibits accelerated breakup when immersed in water. The applicator includes a hollow, cylindrically shaped member which holds a pledget. This cylindrically shaped member is constructed of a water-soluble or water-dispersible material and has a wall with a thickness of less than about 0.05 inches (about 12.7 mm). A plurality of grooves are formed in the wall in a predetermined pattern to accelerate breakup of the applicator into small unrecognizable pieces. The grooves have a depth of between about 5 percent to 75 percent of the thickness of the wall. The deeper the grooves, the shorter the time period needed to breakup the applicator.
